Since 2012, socialhams is available for amateur radio operators. All functions of our platform are free for all registered members and this is not going to change in the future. Nevertheless we have decided to introduce finer structured memberships. The actual membership is displayed in a seperate block on each members profile page.

CATbox is a modular computer aided transceiver (CAT) interface system comprising four standalone matrix board cards. One, or at most two, of these cards can be contained in a Hammondbox – the CATbox. A MAX233 chip and a regulated power supply are common to all the cards. The MAX233 chip solves the problem of converting from the rig’s TTL computer interface voltages to those of the RS232 connection on the computer.
